Sustainable production of mangrove oyster Crassostrea gasar (Adanson, 1757) in Rivers State, Nigeria
The mangrove oyster, Crassostrea gasar inhabits the estuarine/coastal mangrove swampland of the Niger Delta. It can be found in the wild attached permanently to mangrove trees and any other hard substrate in the water. It thrives well in brackish water with a wide salinity and temperature range. The oyster has a high economic value and is accepted both locally as food. The table sized mangrove oysters sold in markets in Rivers State are from the wild. The culture potential of the oyster is yet to be explored in the State; despite the fact that details of culture techniques for the mangrove oyster have been fully documented by scientists at the African Regional Aquaculture Central Nigerian Institute for Oceanography and Marine Research, (ARACINIOMR). This paper highlights techniques for the production of table sized oyster and environmental issues that could affect long term sustainable oyster farming.
